That's what I thought.From what I understand, a Part 15 transmitter that's strictly for personal use is not subject to Music Mafia extortion... oops, I mean license fees... since it isn't being used as a broadcaster. No different than playing a radio in your back yard. If your neighbors hear it, then it's not intentional.
I do hope to eventually expand (maybe to the end of the block haha), so I'll worry about it then.
For the moment, however, it's basically equivalent to a living room jukebox that happens to be "streaming" music to a hifi system via AM radio, and that "stream" happens to be "unintentionally" receivable on any AM radio within a few hundred feet.
